SPECIFICATION forming part of Letters Patent No. 769,391, dated September 6, 1904.

Application filed January l2, 1904. Serial No. 188,758. (No model.)

To (1U 11171111711/ it 71mg/ cm1/cern:

Be it known that l, HENRY H. LYON, a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented certain new and useful improvements in Boiler-Feeders; and ldo declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to malte and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in boiler-feeders; and the object of the invention to produce a device of this character especially adapted for use for feeding purposes for boilers, &c., and comprises an apparatus which is simple in construction and so arranged that water is allowed to enter under pressure the pump-cylinder, and bythe utilization of steam admitted to the cylinder said water is caused to be raised by the action of the steam, thus providing means which is automatic in its action as long as the supply of water is fed to the cylinder and acted upon by steam.

rlhe invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, which with the letters of reference marked thereon form a part of this application, in which drawings similar letters of reference indicate like parts in the views, in which4 Figure l is a vertical sectional view through the cylinder. Fig. 2 is a vicw showing the same as applied to a boiler.

.Reference now being had to the details of the drawings by letter, A designates a cylinder which may be of any suitable shape and size and provided with an inlet-valve-regulated pipe B and an exhaust or outlet pipe (l, each of which is provided with suitable valves B. Mounted within the cylinder, which is supported upon a boiler or any suitable rcceptaclc, are the guiderods E, which are shown in the drawings as having threaded connection with holes formed in the under face of the top of the cylinder, and the lower ends of said guide-rods are bent at an angle to form means for limiting' the downward movement of a iloat l), which is contained between said guide-rods and has a vertical play or d isplaccment within the cylinder. Said float, which may be made of any suitable material and of any suitable shape, is illustrated as being hollow and having Yits top D' tapering to a point. hlounted in the aperture in the top of the cylinder is a flanged valve casing F, provided with flanges F, which rest upon the top of the head of the cylinder and adjacent to the marginal edge of the central aperture therein. ing contains valve-seats (i and H. An annular groove or recess is formed in the circumference of said valve-casing and is designated in the drawine's by letter Q, and ports l lead through the wall ofthe casing into said groove or recess, forming a means of exit for air from the interior of the cylinder tothe atmosphere through the port A.

A valve-stem K has an integral valve L, which valve is adapted to contact with the scat G upon the inner circumference of the valvecasing, and a second valve M is provided at the lower end of said stem l( and'is preferably of an arca substantially twice the area of the valve L and is designed to contact with the seat H to close the opening into said valve-casing. The under face of the valve M normally rests upon the apex of the top of the float l) and is designed to be raised by said float as water under pressure is turned into the cylinder. A third valve (designated in the drawings by letter' N) is formed integral with the valve-stein and has a series of perforations P extending through thc same, the circumference of the valve N being of such a size as to snugly lit the bore of the valveasing and to close the ducts l, leading' into the annular recess Q, when said valve-stem is raised by means of the float described.

Leading into the top of the valve-casing is a pipe R, through which steam is admitted, said steam-pipe being shown in the drawings as communicating with a boiler.

Said valve-cas- IOO In operation water to be fed to a boiler is admitted under pressure from any suitable source of supply through the pipe B into the cylinder A, and any air contained in the cylinder will be forced out -by the water rising in the cylinder. As the air is forced from the cylinder it passes through the apertures P in the valve N and through the ports I into the annular recess Q and thence to the atmosphere through the port A. As the water rises in the cylinder the iioat is raised by the water until the pressure due to its displacement overcomes the pressure of steam in pipe R, which tends to keep the valve L on its seat Gr. It will be understood that in the operation of my apparatusv pressure of steam tends to bear upon the upper surface of the valve L and tends to hold said valve seated and that when the upward pressure of the float is suflicient to overcome the pressure of the steam resting on the valve L the latter will suddenly rise from its seat. At the same time the valve N will be raised so that its circumferencewill close the ports leading to the annular recess Q, thus closing communication of the interior of the cylinder with the atmosphere. The steam will then rush in from the pipe R by the valve L through the apertures P and by the Valve M and into the cylinder, and the pressure of the iniiowing steam will force the water or fluid contained within the cylinder through the discharge-outlet C.

In practice the area of the valve M is made y of such a size that the downward pressure of the column of steam will always exceed the pressure used in the displacement of the float D.

When the air is admitted to the cylinder, the contents of the latter are forced through the discharge-outlet C until the displacement of the iioat D is no longer able to support the valve-stem K, after which the latter falls to the position shown in the drawings. When this point has been reached, the steam which is then contained in the cylinder escapes through the apertures P and ports I and the annular recess, with its exit-ports, to the atmosphere, thus enabling' the supply which, as has been stated, is fed in under hydrostatic pressure, as by placing the inlet-valve below the source of supply, to again enter the cylinder, after which the cycle is continued as long as the supply continues. The valve M and its seat prevent the water from passing out through the top of the cylinder should the steam-supply be cut 0E, for the pressure due to the displacement of the float will effectually close the valve M against its seat. Therefore if the steam is throttled the water will flow into the cylinder until the valve M is closed, and if the supply of water is cut olf or exhausted the contents of the cylinder will be forced out until the valve L closes against its seat, thus preventing further ingress of steam.

From the foregoing it will be observed that a practically automatic apparatus is produced which will work only as long as supplied with the water under pressure to be fed.

In practice while a hermetically-closed float may be used I prefer to leave the float D open at the bottom, as by this means the action of the float may be rendered very much more delicate, not requiring the same to be made of any heavy material. The advantage gained by using the float open at the bottom is shown by the fact that when steam is admitted to the cylinder a column of water is maintained within the float until sucha time as the water surrounding the latter is discharged until it reaches the bottom of the oat, at which time the water contained thereon will flow out, quickly releasing its displacement pressure and allowing' the valve L to reach its seat quickly, thereby preventing the loss of steam through the ports I.

IVhile my apparatus is adapted especially for use in feeding boilers, the apparatus may be of any suitable material, as lead, tin, rubber, earthenware, Sac., is simple in construction, and easily controlled, the speed of the apparatus being controlled by the throttling of the steam.

While I have shown a particular construction of apparatus embodying the features of my invention, it will be understood that various details of construction may be employed, if desired, without in any way departing from the spirit of the invention. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A boiler-feeding apparatus comprising a cylinder, water supply and exit pipes, a iioat mounted within said cylinder, a valve-.casing communicating with the cylinder through which steam under pressure is admitted, a valve-stem mounted within said casing, `and valves carried by said stem, one of said valves being normally held closed by pressure of steam from the pipe communicating with said casing, the other valve adapted to rest upon said float and be raised by the latter as water under pressure is admitted to the cylinder, and valve mechanism for controlling the communication between the cylinder and the atmosphere, as set forth.

2. A boiler-feeding apparatus comprising a cylinder, a water-supply pipe leading thereto and an exit-pipe leading from the cylinder, a float mounted within said cylinder, rods secured within the cylinder and provided with angled ends and serving as guides for said float, adapted to limit its downward movement, a valve-casing communicating with the cylinder, a valve-stem mounted therein and having valves adapted to control the exit of air from the cylinder to the atmosphere, and also the supply of steam under pressure to vthe cylinder, said valve-stem being raised by IOO ISO`

the float as water under pressure is admitted to the cylinder, as set forth.

3. A boiler-feeding apparatus comprising a cylinder' with a water-supply pipe leading' thereto and an exit-pipe leading therefrom, a oat mounted within the cylinder and guides for said float, a Valve-easing communicating with the cylinder, the circumference of said Valve-casing having an annular recess with ports communicating with the atmosphere, a valve-stem mounted within said easing, a valve at the lower end of said stem adapted to he raised by the end of the float, an apertured valve upon said stem designed to close communication to the atmosphere as the valvestem is raised, the latter communication through the valve-easing for the admission of steam under pressure to replace fluid which has been fed into the cylinder, as set forth.

ln testimony whereof I hereunto atlix my 2O signature in presence of two witnesses.
